SHOCK-LOADER. I

Specification of Letters Patenti Patented Sept. 2, 1919.

Application led June 1, 1917. Serial No. 172,313.

To all whom t may concer/n Be it known that I, WILLIAM rERNST KOEPKE, a citizen of the United States, and a resident of Sisseton, in the county of Roberts and State of South Dakota, have invented certain new and useful Improvements in Shock-Loaders, of which the following is a specification.

This invention relates to a device for loading hay shocks or grain, and the like and in particular to a device which may be readily mounted 'upon or removed from an ordinary wagon. The objects of my in vention are to produce a device which may be inexpensively constructed and which may be readily applied to an ordinary wagon of standard size and which will be rapid and eficient in operation.

In the accompanying drawingi Figure 1 is a front elevation of the device,

Fig. 2 is a plan View thereof and Fig. 3 is a detail sectional View on line 3 3 of Fig. 2.

10 is an ordinary wagon body of standard size, fromwhich the bed has been removed, and which is provided, as is usual, with four vertical stakes 11. 12 is a frame constructed of heavy wooden beams or `of steel, and'is of such size as to it exactly between the stakes 11 of the wagon. Approximately midway of the length of the frame 12 there are two cross pieces 13, separated a sufficient distance to permit the ,insertion of an upright 14, which is rigidly attached to said cross pieces. This upright is made of sufficient length to permit the loading of large shocks into another Wagon, and may be, for example, -twelve feet long. It is firmly held in position by means of braces 15 to the side member of frame 12 and braces 16 to cross pieces 17 between the side members of the frame.

From the top of upright 14 and at right angles to the central longitudinal plane of the frame 12 there extends a horizontal beam 18 of suitable length, and suitably braced to maintain it rigidly in position as by means of braces 18, From this beam is suspended a track 19 by suitable hangers 20, and adapted to carry a wheeled carrier 21. This carrier is provided with suitable pulleys 22, to one of which the hoisting rope 23 is attached. A s econd pulley 2 4 provided with a hook 25 is placed on this rope between the pulleys 22. This rope then passes over a pulley 26, mounted at the end` of horizontal beam 18 and of size sufcient to permit the rope to clear both the track and the upper side of the beam. From here the rope 23 passes over other pulleys 27, 28, 29 along the horizontal beam and down the upright to hoisting drum `30. The pulleys may be advantageously provided with guards to prevent the escape of the rope as shown.

Hoisting drum 30 is loosely mounted on transverse shaft 31 which is mounted in bearings 32 attached to tlie side members of frame 12 and directly below uprights 14. The drum is provided at each end with guards or shields 33, 34 and also with a central shield or partition 35, the purpose of which will hereinafter be explained. To one of the guards or shields 33 is removablv attached by bolts or otherwise a flange 36 which is part of asleeve 37, also loosely mounted upon shaft 31. The end of this sleeve is provided with clutch member 38 and with a groove 39 in which engages an operating lever 40. Coperating clutch member 41 is rigidly attached to shaft 31. Lever 40 is pivoted at 42 on transverse stay 43 attached to bearings 32, and is provided with a spring operated pawl 44 which engages with arcuate ratchet 45 mounted on one ofthe cross pieces 13. By operation of lever 40 drum 30, together with clutch member 38 may be moved on shaft 31 to connect or disconnect the clutch.

Shaft 31 is extended at one end beyond bearing 32 and is provided with a fixed sprocket wheel 46, which is operated by a chain 47 operated from sprocket wheel 48 removably attached to the spokes of one of the wheels of the wagon.

The shock lifting fork is attached to the hoisting hook 25 and is formed of two semicircular forks 49 and 50 of which one, 49 is larger than the other. The tines of the forks will thus not engage at directly opposite points of the shock to be loaded. The central tines 51, 52 of each fork is also bent laterally also to prevent engagement at exactly opposite points of the shock.

The tines of each fork are attached to semicircular supports 53, 54, and are reinforced b bands 55, 56. To each support a yoke 5 58 is attached, which terminates in rods 59, provided with eyes 61, 62.
